Welcome to the SignalBox wiki!

Current Project Status (1 March 2017)

• DCC "Driver" has the core functionality of being able to transmit any bitstream, queue multiple bitstreams, and cleanly transition between them.

  • This code is somewhat OOP "mega-class" in design as a result of being written on-the-go. It will be refactored into a much more Protocol-Oriented design.
  • Currently this goes to extra lengths to handle the RailCom cutout period itself. I'm increasingly expecting to move away from this approach, which will simplify the design a lot, in concert with the above refactor.

• Currently working on different approaches for the AVR-based Booster and RailCom detector boards.

• Procrastinating on finishing the wiki pages below for DMA.

Swift on the Raspberry Pi

Swift is my favorite programming language of the moment, and it's ideal for working with the Raspberry Pi hardware. These pages document everything I've learned in the process.

• Swift on Raspberry Pi
• Accessing IO Peripherals from Swift
• Swift Pointers
• Integer Types
• GPIO
• Clocks
• PWM
• DMA
• Using DMA with the PWM
• Using DMA directly with GPIO
